APPARATUS FOR STAMPING BILLETS.

SPECIFICATION forming part of Letters Patent No. 445,291, dated January 2'7, 1891.

Application filed August 16, 1890. Serial No. 362.200- (No model.)

To all whom zit may (o/warn.-

Be it known that l, FRANCIS H. TREAT, of Chicago, Cook county, Illinois, have invented a new and useful Improvement in Apparatus for Stamping Hillets, of which the following is a specification. v

The object of my invention is to provide for stamping numbers, letters, or characters into hot blooms, billets, or metal bars as they are traveling to their place of delivery; and theinvention consistsin the features and combinations hereinafter described and claimed. In the accompanying drawings, Figure 1 is a broken side elevation of my improved stamping-nmchine; Fig. 2, a plan View of the same, and Fig. 2 line 3 of Fig. 1.

A is an I-beam, forming the base orsupport of the machine, and also forming a track for the conveyer; 13, the con veyer; C, a billet traveling on the conveyer; I), side rails or guards; E, stationary rovoluble rollers having their bearings in the side rails; F, crossarms pivotally connected at one end to a stud f, secured to the side rail or guide 1), its other end being flexibly connected to said side rail; G, a shaft mounted on the cross-arms, and g a hand-Wheel on the shaft for turning the same; I], a stampinghead on the shaftadapted to be rotated or oscillated by means of the hand-wheel to bring itiuto contact with the billet; 71, dies in the stamping-head adapted to be forced into the billet by the rotation of the shaft, and 7t set-screws for curing the dies in the stamping-head.

Inthe man ufactu reofbillets ofsteel it is generally desirable to keep a record of each heat, and as the billets are generally sold by chemical specification it is also desirable that the billets be so stamped or marked as to indicate the heat from which they come. For instance, if all the billets of a given heat be stamped or marked 100 and a chemical record is kept of this heat it will of course be apparent that any billet bearing the mark 100 is of the chemical composition shown by such record. This stamping or marking of the billets is of course most easily done while they are hot; and the object of my invention is to provide for stamping them as soon as formed, and

a sectional view taken in preferably while they are being conveyed to a place of delivery.

My improved stamping-machine consists, essentially, of asegmental roller mounted on a horizontal shaft adapted to be rotated by a hand-wheel or otherwise, the roller being provided with a suitable die or dies to form the figure, letter, or character desired to be cut or impressed on the billet.

I am not aware that any marking or stamping machine has ever been heretofore used in connection with a conveyer having traveling rollers, and so one feature of my invention may be considered as consisting in providing a stamping or marking machine for such a eonveyer.

As the billet which is being carried forward on the conveyor comes under the segmental roller, the operator, by turning the handwheel, causes the part containing the die or dies to revolve forward, and this forces the die down in the billet to the extent necessary for marking purposes. Of course the proportion and arrangement of the parts are such that the die will be required to out into the billet, but not farther than necessary to plainly mark it.

The segmental roller may be provided with a single die or with any number of dies desired, each die being of course adapted to cut a single figure, letter, or character. For instance, if it be desired to mark the billet 9 the segmental roller will only be required to have a die adapted to cut this one figure into the billet, while if it be desired to mark the bi]- let 927 the segmental roller will be required to have three dies, the first adapted to cut figure 9, the second figure 2, and the third figure 7. These dies are preferably capable of being put into the segmental roller or taken out therefrom at will, being inserted in sockets in the roller and held in place by a setscrew.

If the segmental roller were alone, it is apparent thatif it should strike down upon the end of a billet it might cause the end to be depressed and the billet thus put out of position for marking. This would be particularly the case if the billets were being carried on a conveyer having traveling rollers. To avoid fulcrumed on one of the traveling rollers not directly under the segmental roller.

As safeguards to the machine, I provide springs to receive and regulate the strain in case the billet should be slightly deformed by theshearing orotherwise. The construction and operation of these springs will be apparent from the drawings.

The cross-arms being pivotally secured at one end and flexibly secured at the other form a flexible and adjustable bearing for the shaft carrying the segmental roller. The pivotal connection is formed by means of an upwardly-projecting lug and the flexible connection by means of a spring above the arm and on the stud, which is secured to the side rail and passes up through the end of the arm. The adjustment. of the arms is effected through the nuts and screws on said upwardly-projecting stud.

It Will be understood that I use the term billet in a general sense, and as meaning a billet, bloom, or other piece of metal desired to be marked or stamped, and that in the same Way I use the term conveyer as meaning, generally, either stationary or traveling rollers or other means employed for advancing the heated metal to a place of delivery.

I claim 1. In combination with a billet-eonveyer having traveling rollers, a stamping-machine above the eonveyer to mark the billets while in their course of travel, substantially as described.

2. In combination with a billet-conveyer, a roller placed above the conveyer, having marking-dies secured therein, and means for operating the roller to bring the dies into contact with the billet, substantially as described.

In combination with a billet-conveyer, a segmental roller having marking-dies secured therein mounted in adjustable bearings, and means for operating the segmental roller to bring the marking-dies into contact with the billet, substantially as described.

4. In combination with abillet-conveyer, a segmental roller having markingdies secured therein mounted in flexible and adjustable bearings, and a hand-Wheel for operating the roller to bring the marking-dies in contact with the billet, substantially as described.

5. In combination with a billet-.conveyer, a segmental roller having marking-dies secured therein, a plain roller in front and rear of the segmental roller, and means for operating the segmental roller to bring the marking-dies into contact with the billet, substantially as described.

6. In combination with a billet-conveyer, a stamping-machine above the conveyer, comprising frame-Work, a roller having markingdies secured therein mounted in the framework, a plain roller or rollers in front and rear of the segmental roller, and springs pressing upon the frame-work to hold the same in position'and permit of its yielding when subjected to undue strain, substantially as described.
